The Motorad 4831KT is a complete engine coolant thermostat housing assembly designed for Ford V8 applications from 1975 to 1997, including Bronco, F-150, E-Series vans, and full-size sedans. Manufactured by an OE supplier to OEM specifications, this kit combines a copper and stainless steel housing with a disk-type thermostat rated to start opening at 192°F (88.89°C), delivering consistent, predictable response to changing coolant temperatures. The offset design and integrated air relief valve help support proper cooling system operation, while the included OEM-style gasket and seal simplify installation without hunting for separate parts. With two mounting holes and a 0.05 in flange, this assembly is built to match original equipment fit. A straightforward, all-in-one replacement for aging or leaking housings on classic Ford V8 engines.
